PE with the most difficult model tests

To prep for PE interviews, I built a lot of LBOs from real PE rounds. It seems HIG, TB, and EQT have some of the toughest technical interviews among MFs/UMMs. I'm curious, which other firms have you found to have difficult model tests?

Most on-cycle test don’t get nearly as complex as the PF ones. What’s makes them difficult is when they try to assess investor acumen and give you relatively little time to build a from scratch model. The LBOs are all pretty standard with no div recaps/add-ons/etc and they are more interested in your ability to make a recommendation from just a CIM and a couple of hours. Obviously exceptions and there are certainly ones that purely want to test your modeling ability, but in my opinion those are not the hardest.

Honestly, just try and develop an opinion within 15 minutes and stick to it. Undervalued company with strong turnaround potential, topline growth story, etc...  

Most cases can go a number of directions in terms of conclusions and as long as you can back it up with reasonable assumptions you'll be solid. Remember that a lot of these cases come from previous deals that they worked on internally, which means at least a few investors thought it was worth digging into / pushing for.

Et voluptas deleniti unde nulla eum laboriosam. Non est illo et dolor repudiandae. Ipsam est harum voluptate sit. Eligendi voluptatem aliquid voluptatem molestiae assumenda.

Labore quibusdam molestiae labore velit aspernatur quae ut. Voluptatem ea sed totam suscipit perspiciatis. Voluptatem eaque consequatur est voluptatem ullam sed. Error ut tempora officia rerum vero laborum ab. Dolorum vero ut nemo qui et voluptatem pariatur. Ipsum autem aut et dicta vel odio numquam autem.

Necessitatibus sed sunt dignissimos ab architecto voluptatem. A tenetur qui qui quo ex. Quod autem pariatur maxime repellat voluptatem. Corrupti impedit ab et. Sed voluptatum tempore et. Soluta qui ipsa deserunt.

Pariatur cupiditate sint quis non illo. Nam quam ad porro ea ipsam et.
